Laz-Boy / Two Recliners

We purchased two recliners, after delivery we discovered that when closing the foot rest there is a VERY LOUD BANG, not a noise but a disturbing BANG ! After two visits by their service technician and conversation with their customer service supervisor. Our request to exchange the two recliners was denied. We were told that we should have reported our concern and disappointment within 3 days of delivery. I advised the service supervisor that we were never appraised of the 3 day limitation and that our sales person did not mention the loud noise either. In summary we are stuck with a Lazy Boy product and are very disappointed with it. Unfortunately there appears that there is nothing we can do. Any suggestions would be most welcome. Joe F. B
